To all 'whom t may concern:

vBe it known that I, JOHN M. Rorrnriiv residingat St.y Louis, Missouri, andfbeing a citizen of the United States', have invented certain' new and useful Improvements in CareUnderframes, of whichr the following is a full,;clear,-and exact description, such aswill enable others skilledin the art to which it appertains to make and to use the same, reference being had tothe accompanying drawings7 which illust-rate the preferred lform ofthe invention, though it`is to be understood tliatthe inventionl fis not limitedr to the exact details o'fconstruction shownand described, as it is obvious'that variousy modifications thereof will Occur Vto persons skilled in the art. In said drawings: l f .Figure l is a planI view of aportion of a car underframe embodying the invention hereinafter described. The gure illustrates portions only of an end sill, abolster, center and intermediate sills of wood together `f with ineansofconnection hereinafter moref fully described, .and it is to be understood that the parts illustrated are duplicated at opposite sides of the longitudinal center of thecar and at opposite ends of the under-Y f frame asis common inv car construction.

.The fpre'ferred forni of l thefr-inventionl would depend upon whetherthe infanufac-` steel castings or to fabricate sheets and sha-pes such are readily obtainable in the open market.

In the structuralform D indicatesthe` draft arm which is illustrated as comprisA ing a single pressed plate of rectangular pan shape with vertical web land jwlth 1ntegral flanges 1a and 2 which may be formed by pressing although it is not essential that.,

such flanges 1fL and 2 be integral as' they may be formed byriveting anglesto the.

Aistiffening and` connecting angle 5 is. secured to the horizontal flange :1210iv the arm D by rivets and to the center-sill y6 by bolts 7.1' Said angle servesto sti-ffenfboth Y' membersandto connectthem.

A=similar .angleS is secured to the inside of the intermediatesill 9,4'. e., on the side of the sill next adjacent center sill Gfandy theliorizontal lleg` of. said angle extends .to- Ward the center sill;vv Y

Extending 'obliquely upwardly from and connected'tol thelower part `ofithedraft' arm is a plate 10 .Which is: riveted towthe horizontalyleg 11 of` angle 8.- This plate` is preferably substantially. co-extensive in length Withlthe draft arm, extendingpracticallyfrom` the bolster. tothe end sill, so

l as to brace and reinforce the.-.draift 'arnr Within the zone of the draft lug hereinafter referred to.-`

The. .plate 10 is providedwith openings 12 to afford ready access tothebolts 7 yand 7 and said openings-do not materially-weakenthe general. structure. f

Immediately back of the endv sill 3v and plate 10 isa pressing 13 resting above the provided lWith. horizon-tal andV vertical flanges adapted for lconnection respectively with the angles 5 and 8 and center'and in-k termediate sills beforeidentified.r

Itis obvious that if such formation vveredesirable, theangles 5,'and 8, plateV 10 and sill' pressing 13 might,allbefcom-bined vin 'a single't pressing, providing .themanufacturer Were-.equipped for itseproduction bu-t there is ran advantage `in the .combination of the plates .and shapes referred to, in lthat they? may be secured in the open marlretfand fash ioned without the yemployment ofthe large presses which Wouldfbe single-pressing.

Itisto be noted that the angles 5 VandS draftllug combined lwhich In service the lateral thrusts which result from draft gear operation arevmet by the plate 110 which braces the draft arm laterally` Where such bracing is most required. Longitudinal thrusts imparted to the draft lug and arm by the couplerand draft yoke areV transmitted( to l t-vvo Wood sills by -the means provided instead of to only one such sill ,ateach side of the center line of the car as heretofore and such sills are in the presenty instance reinforced and so as to jointly absorb bufflng stresses.

The cast embodiment of the invention comprises a main web portion 16, draft stops 17, horizontal flange spectively,= and vertical flangesQO'andQl all cast asaninteger so'. combined and adapteed for connection ,with Wood Acenter and in# connected.

'It Willfbe notedthat the horizontal webl):I with the, integral verticalllanges 2Oand. 21 'f' span the 'distance between the. centerslh 6 and the intermediate sill i9 with; which i :the .f

Integraly with the parts referred to,f is' :a

shoulder 28Wliich risesvertically from the` `plane of the portion 19 :of the casting andi serves.` as. a `reinforce.abutment atj the vvrear or inner side of the end sill `Thus -far'the vfcast.metal' embodiment ofV Vnectionsare. desirable, two of whichvr occur` at each end Aof the car.

It may be desirable to connect inforcements the sill re-V a plurality of H shaped beams 29 which, as will be noted in Figs l() tolQ inclusive, are riveted tothe bolsters and'to the'cast pan shaped connectors before referred to. In this embodiment the beam is disposed with its web vertical and with its top and bottom flanges horizontal in which case the bottom flanges are riveted as before described yand the top anges may serve as supports for the flooring F of the car.

Inv Figs. 10 to 12 inclusive a casting 30 is shown as abutting the rear of the bolster B and is riveted directly to the bottom flanges of the H beam before referred to, thereby resisting any tendency of the bolster to rotate about its longitudinal axis.

As in the structural form rst described, the cast pan and draft arm distribute buffing shocks to a plurality of sills instead of to a single sill,-meanwhile bracing both of the sills with which it is connected and providing a convenient and readily applied means for reinforcing wood or composite underframes of railway cars.

It is to be noted that neither form of the device necessitates the 'removal of any ofthe n longitudinal sills or the floor 'of the car nor the disniounting or alteration of the bolster. Also, the sills are connected by the panshaped members in segregated pairs.

TWhat I claim is:

1. In combination, a bolster, a plurality of spaced sills, a horizontally'disposedpaii with vertical flanges paralleling and being connected directly to said sills thereby connecting them, said pan being removable without affecting said bolster, and a draft lug rigidly connected with said pan.
